Looping Through Arrays Within An Array, If Particular Array Has A Specific Word, Grab That Array
I'm trying to create a search function where a search word is passed through (for example, 'Food' or 'Gym') and the function will loop through the arrays in the array, if that word
Solution 1:
Your question is not exactly clear. Is this what you need? It returns the nearest array that contains the matching word. I used RegExp test to find the matching word, if you need to find the exact words, use === instead since test is not as performant. I only put there since you can write some more versatile random RegExp with it.
functionwordFilter(keyword, list) {
var filter = [];
recursiveFilter(keyword, list);
functionrecursiveFilter(keyword, list) {
//Loop if list is array, otherwise test if it matches the keywordif(Array.isArray(list)) {
for(var i = 0; i < list.length; i++) {
if(recursiveFilter(keyword, list[i])) {
//This unlikely to return true, I just put it there to make sureif(Array.isArray(list[i])){
filter.push(list[i]);
} else {
filter.push(list);
}
break;
}
}
} else {
var reg = newRegExp(keyword);
return reg.test(list);
}
}
return filter;
}
Solution 2:
functionwordFilter(list, keyword) {
var returnVal;
list.forEach(function(childList) {
childList.foreach(function(value) {
if (value === keyword) {
returnVal = childList;
}
})
});
return returnVal;
}
console.log(wordFilter([["test", "monkeys"], ["car", "airplane"]], "test"));
Solution 3:
// Filter list with search keywordfunctionfilter(keyword,list) {
// placeholder for matchesvar filtered = [];
// loop through listfor (var i = 0; i < list.length; i++) {
var store=list[i];
for (var y = 0; y < store.length; y++) {
// if match keywordif(store[y]==keyword){
// push that store into filtered array
filtered.push(list[i]);
}
}
}
return filtered;
} `
Solution 4:
As a follow up of my comment, here is a sample code using indexOf()
instead of match()
in order to know if a string contains a substring. I'll also use filter()
and join()
instead of two for loops.
var findIn = functionfindIn(needle, haystack) {
return haystack.filter(function(el) {
return el.join(' ').indexOf(needle) > -1;
});
}
, list = ["Mikes Gym", "21 Rosenberg Road", "Heidelberg", "Come get your ice", "5", ["onsequat. Phasellus diam .", "malesuada in. Integer eget molestie mi. Etiam a"], "9104-1059", "Gym" ], ["Mikes Cafe", "21 Rosenberg Road", "Heidelberg", "Come get your ice", "5", ["onsequat. Phasellus diam .", "malesuada in. Integer eget molestie mi. Etiam a"], "9104-1059", "Food" ], ["Mikes Hairdresser", "21 Rosenberg Road", "Heidelberg", "Come get your ice", "5", ["onsequat. Phasellus diam .", "malesuada in. Integer eget molestie mi. Etiam a"], "9104-1059", "Hairdresser" ], ["Mikes Nightclub", "21 Rosenberg Road", "Heidelberg", "Come get your ice", "5", ["onsequat. Phasellus diam .", "malesuada in. Integer eget molestie mi. Etiam a"], "9104-1059", "Club" ], ["Mikes Groceries", "21 Rosenberg Road", "Heidelberg", "Come get your ice", "5", ["onsequat. Phasellus diam .", "malesuada in. Integer eget molestie mi. Etiam a"], "9104-1059", "Shop" ] ]
;
console.log(findIn("Food",list));
The conditional part, return el.join(' ').indexOf(needle) > -1;
, might be adapted to your needs, using lower case match only, regular expression or any other method that will return a boolean.
